Maybe we don't understand the feature in the documentation, but this
isn't the refresh_on_change functionality. In the Tophat tool XML
there are no refresh_on_change="true" attributes, you are talking
about a conditional tag which when changing will refresh the page in
order to expose different parts of a form depending on then value
chosen, this is a different use case.

The feature we thought exists from the wiki docs is a utility
refresh_on_change="true" attribute that you can put on any input param
tag which will cause the page to refresh with the changed state when
you change the param. It's supposed to replace the deprecated pages
tags.  Once we started needing to make more complex form logic you
realize that this is not just very useful but necessary.

Here's one example:

   <param type="data" name="dataset" refresh_on_change="true"
label="Select a file from you history" />
   <param type="select" multiple="true" name="dataset_values"
dynamic_options="get_options_from_file(dataset.file_name)" />

If the user changes their selection of data from their history it
should refresh the page and call the dynamic options again to load the
other select menu with the choices from the new file. Currently you
have to do this with repeat or pages tags which is really cumbersome
for the user in the UI or doesn't allow workflowing, respectively.

Does this feature I describe to replace the deprecated pages tags not
exist or just isn't fully implemented yet?
